An introductory performance, preceding and preparing for the principal matter; a preliminary part, movement, strain, etc.; especially (Mus.), a strain introducing the theme or chief subject; a movement introductory to a fugue, yet independent; -- with recent composers often synonymous with overture.
To play an introduction or prelude; to give a prefatory performance; to serve as prelude.
To introduce with a previous performance; to play or perform a prelude to; as, to prelude a concert with a lively air.
To serve as prelude to; to precede as introductory.
